*Why do I need a 65W 15V, instead of any other model? A 65W 15V charger could support versatile Surface devices with quicker charging speed with higher power rate.

* Why is it hot? Is it overheating? Is it safe? When the power supply is working/charging, it will become warm/hot sometimes, depending on battery percentage and the working mode of the device. It is not overheating, as long as the outer material is not melting or spreading abnormal odor. We cooperate with TUV approved partner, guaranteeing material safe.
